The Double "A" arm rear suspension has been designed as an optional rear suspension to suit the Piranha series II.

This new rear end fits into exactly the same position as the Piranha series II single arm rear suspension, all bar work remains the same.

The Double "A" Arm rear has the following advantages over the standard Piranha single arm rear suspension.

  • More control over full suspension Camber
  • Stronger design spreading loads over a larger area.
  • More resistance to acceleration torque reaction effects.
  • Increased droop available without going into positive camber.
  • More suspension travel.
  • Better resistance to frontal wheel forces from severe bumps.
  • Increased braking capacity.

The construction features common length "A" arms, all arms can be made out of one common jig. The suspension geometry features progressive negative camber which equals precise stability in severe offroad conditions.


Designed to suit the Piranha series II buggy, but also a valuable component for any home built offroad buggy.

The plans include detail 3D drawings of all the parts that need to be made, rear housing, uprights, driveshafts, drive hubs, wheel hubs, axles, chain adjusters, disc rotor, caliper mount, bushes, pivot pins & many detail assembly & exploded views.

Without doubt the most comprehensive detailed plans available.

NOTE: The Double "A" arm suspension plans cover the complete rear suspension only, not the chassis or other buggy parts.

Barracuda Chassis Brackets

This drawing is the file to cut all of the mount brackets for the Barracuda chassis. This design is similar to the plans, but refined with a few holes to make the component lighter as well as tagging together like a jigsaw puzzle.
